{"abstract":"This study investigates the experiences and challenges faced by workers in the gold mining industry of Mt. Diwata, Monkayo, Davao de Oro, focusing on miners, ball mill operators, gold buyers, and jewelry makers. The research employed a multiple case study approach, conducting in-depth interviews with four participants representing each role. Findings reveal that despite the demanding and hazardous nature of their work, participants are primarily motivated by the need to support their families. Key challenges identified include life-threatening conditions, health risks, and security threats, with workers demonstrating resilience through personal sacrifices and reliance on family and faith. Insights from the study underscore the importance of education in improving life circumstances and highlight a strong demand for increased government support. Recommendations include enhancing educational opportunities, improving health and safety standards, providing economic support, and strengthening community and government initiatives. These measures aim to address the challenges faced by mining workers, improve their quality of life, and promote sustainable mining practices.","abstract_source":"original","authors":["Rubilyn Barrios","Rhyan Mike Bacaro","John Dhell Cedeño"],"date":"2025-04-15","doi":"10.70838/pemj.350407","id":4880,"issue":4,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"6f71d76ec1cd65d7cd05fa7cba60b71b291925525691c3c61cc2c632e80bad58","schema":"scimatic-article/1","title":"Transforming Gold Ore to Jewels: A Multiple Case Study of Mining Industry Players","volume":35}
